どが用いられる。A transfer pattern layer 3 is formed on a resin layer 2 provided on the surface of a resin molded product 1. The transfer pattern layer 3 is formed of a dye and pigment of an appropriate color and a resin binder, and is formed in an arbitrary pattern. As the resin binder, a thermoplastic resin is generally suitable, for example, a vinyl chloride-vinyl acetate copolymer, polyamide, polyester, polyacryl, polyurethane, polyvinyl acetal, chloride rubber, or the like is used.

図１に示すように反りが発生しない。The method of forming the transfer pattern layer 3 is as follows.
The transfer material according to one configuration layer adhered to the resin layer 2 surface, tree
Transfer is performed at a temperature lower than the thermal deformation temperature of the resin molded product and higher than the softening point of the resin layer . When the transfer heat is applied, the resin layer 2 is mainly softened because there is a difference between the transfer temperature and the softening point of the resin molded article 1. After that, the resin layer 2 tries to shrink, but the resin molded article 1 maintains its shape and prevents the resin layer 2 from shrinking. Therefore, the resulting transfer painting molded product is
No warping occurs as shown in FIG.
